LEATHER-LACE CUTTER.

SPECIFICATION forming part of Letters Patent No. 704,294, dated July 8, 1902. Application filed June 21, 1901. Serial No. 65,517. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAF OLSSON BJOR- KANDER, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of Wisconsin, have invented a new Leather-Lace Gutter, useful where leather lace is needed to be cut from round pieces or strips of 1eathera tool that can quickly be regulated to out different widths and adjusted to the different thicknesses of leather to be cut-of which the following is a specification.

The guide of the cutter is made from material that is springy, so as to allow unevenness in the thickness of the leather to pass through in first cutting and after the lace is out adapted for splitting it or truing upany side of a lace to a perfectly uniform width or thickness to its opposite side.

The invention consists of the construction and the arrangements of the parts thereof according to the following description and claims.

In the drawings, Figure 1 is a perspective view of the lace-cutter. Fig. 2 is a section on the line 00 cc of Fig. 1, showing the base-plate and certain detail parts mounted thereon. Fig. 3 is a View of the regulating-plate and other detail parts. Fig. 4 shows the guide.

Similar numerals of reference indicate corresponding parts in the several figures of the drawings.

The numeral 1 in the drawings designates a circular wooden plate onto which all the other parts are directly or indirectly connected. The knife 2 is vertically driven into the wooden plate, so as to have its side parallel with the guiding-surface of the vertical lip 12 of the guide, with its edge rising perpendicularly from the surface of the wooden plate. The center screw 3 forms the regulating-plate pivot and holds all the adjustable parts to the case or wooden plate 1, and by this screw-pivot the tension is sufficiently regulated to hold the regulating-plate 6 rigid and retain its adjustment while laces are being cut.

The indicator 4. is a small brad driven in the wooden plate near by and in front of the scale 8 for indicating the movements of the scale.

Athin brass spring 5, with circular opening 17, is mounted on the center screw 3 over the regulating-plate 6, with circular opening 16 on the pivot 9 between the guide and thumbnut lO forpreventing the thumb-nutunscrewin g from oscillatory manipulations of guide 15.

The regulating-plate 6, Fig. 3, made from sheet spring-brass or other suitable material, has a circular opening 18, fitting center screw 3 snugly, by which it is pivotally fastened, mounted on said center screw under the end 17 of spring 5 to the wooden plate. The pointed or tapering end of the plate is rolled upward, thereby making a thumbhold 7 for manipulations. The scale 8 is made at the opposite end of the plate.

The pivot 9 for holding the guide is made with its lower end rigidly fastened at 19 and the upper end of the pivot screw-threaded to fit thumb-nut 10.

The guide 11, Fig. 4., is made from sheet spring-brass slit, doubled, and bent in such manner as to make the end of the lower side the perpendicular lip 12 and the end of the upper side the horizontal lip 18 and upper side 14 of guide a trifle wider than the lips, thus preventing the guiding-lips from coming in contact with the knife where a keen edge is wanted for cutting the laces. Toward the rear end of the guide is a circular opening in the upper side 21 sufficiently large to allow to the guide enough tilt or tiltage to adapt itself to and rest close on the surface of the base, with the perpendicular lip and the opening of the lower side 20 made to fit pivot 9, Fig. 3, snugly when mounted thereon to insure accuracy for adjustments. The end of the horizontal lip is made to fit closely and so as to run easily up and down the face of the perpendicular lip and the guide by inherent expansive force. When released by unscrewing thumb-nut 10, the horizontal lip 13 will rise with its end closely along the surface of the perpendicular lip 12. Thus by the thumb-nut 10 on pivot 9, on which the guide is mounted, it can by expansion or compression be adjusted to any thickness of leather within the guides capacity, and the length of guide in combination with the springy material from which it is made, can be so fitted as to allow unevenness in the thickness of the leather without interruption to pass through when cutting laces therefrom.

In preparing leather for cutting laces disks are cut in any preferred manner, having a lace begun at the periphery of each disk. This lace end is placed inside the knife while the guide is turned away therefrom. The guide is then turned till it engages the cutter-knife, with the guiding lips 12 13 pressing the leather with the desired adjustment. The lace is then drawn out at right angles from the guide against the cutting edge and along the inside of the knife.

Changes in the form, proportions, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having described the invention and its use, .What is claimed as new is- 1. In a lace-cutter the combination of a graduated regulatingplate pivoted 011 a suitable support, a spring-guide pivoted thereon and having two arms terminating in vertical and horizontal lips and a cutter fixed in the support, adjacent to such lips, as set forth.

2. In a lace-cutter the combination of a 25 graduated regulating-plate pivoted on a suitable support, a spring-guide pivoted thereon and having two arms terminating in vertical and horizontal lips, a springuard between the upper arm of the guide and its clamping 3o GUSTAF OLSSON BJORKANDER.
